done must be done according to the applicable technical manual as specified by PMS. You must complete the required  PQS  for  this  equipment.  For  more  detailed information, refer to NSTM, Chapter 584, “Stern Gates, Ramps,  Bow  Doors,  Turntables,  and  Water  Barriers.” Also,  a  copy  of  NAVSEA  0916-LP-018-5010, Operation   Manual   for   Bow   Ramp   System   (U)   LST 1182-1198,  may be very useful. ELEVATORS U.S.   Navy   shipboard   elevators   are   either   the electromechanical  winch  type  or  the  electrohydraulic ram type. Elevators are classified by their functional use. The  following  designations  are  typical  of  elevators installed  in  Navy  ships: l  Cargo  elevator l  Weapons  elevator l  Ammunition  elevator Figure 8-5.—Auxiliary ship elevator. l  Personnel  elevator l  Medical  evacuation  (MEDEVAC)  (casualty) elevator l  Aircraft  elevator Some  elevators  serve  several  functions.  For example, aircraft elevators are used to move weapons, cargo,  personnel,  and  support  equipment.  Weapons elevators can serve as cargo elevators and can be used to evacuate personnel casualties in a mass or medical emergency  situation.  Figures  8-4,  8-5,  and  8-6  illustrate some of the types of elevators aboard U.S. Navy vessels. Pay particular attention to the location of components and safety devices on each type of elevator. The  complexity  of  elevator  systems  is  increasing and   so   is   the   degree   of   maintenance   and   training required to keep them operational. It is a must that you qualify  and  pass  a  PQS,  Ordnance/Cargo  Elevators, Operation/Maintenance.  Only  qualified  personnel  can work on elevators.
